Rechargeable lithium types require more careful monitoring than other
rechargeable types. Dedicated packs and chargers enable the manufacturer
to control this. Making trchargeable AA cells available could lead to
dangerous problems if carelessly charged.
The new eneloop very low self discharge cells from Sanyo overcome much
of the objection to NiMH, although currently those available are limited
to 2000mah capacity.

AA lithium batteries, like the Energizer E2, are not rechargeable.
Lithium Ion batteries are rechargeable but are not made as AAs because
their voltage is too high (3.6V) to risk selling them. The appliances
designed for AA cells expect voltages around 1.2 to 1.5V per cell. It
would be possible to replace 2 series aligned AAs with one LiIon, but
sooner or later some dick-head would mess up, blow up his gear and the
lawyers would have a field day.

Some AA battery cameras can also accept a rechargeable CRV3 lion battery
eg Many Olympus models that take AA's. One CRV3 takes the place of 2
AA's so the battery compartment for these is oval shaped.
There have also been a few cameras eg Ricoh Caplio G3 and some Samsung
models, that came with a rectangular Lion battery but could also accept
2 AA batteries.

....and the cells inside a LiIon CR-V3 are, in fact, rechargeable
14500 (AA) lithium-ion cells ... contrary to what several posters have
asserted in this thread. Yes, they exist, and standalone chargers designed
specifically for cylindrical lithium-ion cells certainly exist too. They
simply are not marketed as routine consumer items, for the reasons cited.

The problem, of course, is that their terminal voltage is 3.6V and it is
far easier to use them in pairs, wired in paralle inside a CR-V3 battery
pack with protective circuitry against LiIon nasties.

The OP asked about AA lithium, not AA lithium-ion. As I
replied above, AA lithium cells are not rechargable.

That is incorrect. Just because a Li-Ion cell has the size and
shape of a AA cell, that does not make it a AA cell. Energizer does
NOT say that their CRV3 (ELCRV3) primary batteries are made from a
pair of AA cells. What they do say is that they're made up of two
CR14500 cells in a parallel configuration. Similarly, a
rechargeable Li-Ion version of the CRV3 would not be made from
Li-Ion AA cells. You're free to take a contrarian view and even
believe it, but you'll be lonely in your belief.

Well then, the battery manufacturers themselves must hold that contrarian
view. Look at the data sheet from Saft, where they refer to their 14500
primary cells as "AA sized lithium cells".

No need. You evidently have a language problem. Of course
they're AA sized, but that doesn't make them AA cells. Are you
normally this dense? How many lawsuits do you think Saft would be
bombarded with if they sold these to the public as AA cells? They
don't and won't and you not only enjoy being a contrarian, you also
have no qualms about embracing asinine views. I'm confident that
this isn't your first nor will it be the last.

Those are special purpose lithium thionyl chloride cells intended for
applications like computer memory backup. They're 3.6 volts and have
huge energy density but only at very low current drains, like below
one mA. They're not consumer items although you can sometimes buy
them in electronics stores. The chemicals in them are rather
hazardous and they should (like all batteries, but especially so) not
be thrown out in the trash when depleted.

IEC 60086 is not online (copies are $$$) but a little googling to
other documents that reference it indicates that while the chemistry
isn't part of the spec, the voltage (1.5 volts) is.

Hmm, it only took a couple of months for you to lose your mind. I
suppose you favor the havoc that would be caused by the availability
of same sized, same shaped, physically compatible lead acid and
Li-Ion batteries? AA is a size only so long as the chemistries used
for them produce voltages that remain compatible with devices that
use AA cells. My cameras that use 4 AA cells *really* like seeing
not much more than 6 volts, and while the 15+ volts provided by
Li-Ion AA cells could really be great for flash recharge cycle
times, the cameras that they're accidentally placed in wouldn't last
very long, and would have voided warrantees. Try manufacturing and
selling super high voltage AA cells that fit in all devices that use
AA cells and see how long it takes for lawsuits to come down so hard
on you that there's nothing left but a greasy stain and the memory
of an absurd position.

AA is a size, not a chemistry.

AA is also a voltage spec of sorts: Sure wouldn't
want a 3.7 volt Li-Ion cell in *my* camera in an
"AA" physical size.
